Abrégé : front page image
(EN) The invention provides a fan speed regulation method and device of distributed network equipment. Fans in a fan frame of the distributed network equipment are divided into fan groups according to the corresponding physical location relation between the fans and board card slot positions; the fan speed in each fan group is jointly controlled, and the fan speed between each fan group is individually controlled; and for each fan group, the following steps are performed: obtaining the ambient temperature in the environment at which the corresponding distributed network equipment is located, the temperature at an air outlet of the single board corresponding to the fan group in physical position, and the temperature of the single board corresponding to the fan group in physical position; obtaining the expected fan speed corresponding to the ambient temperature by querying the corresponding relation between the ambient temperature and the expected fan speed according to the obtained ambient temperature; and performing speed regulation decision on the fan speed of the fan group according to the expected speed, the temperature at the air outlet and the temperature of the single board corresponding to the fan group in physical position. By adopting the scheme of the invention, the accuracy of speed regulation can be improved and the energy consumption is saved.
